When I click on the omnibox, I can't go back into game typing or moving with arrow keys. This also happens when I want to take a screenshot using Cmd+Shift+4+Space Bar.
captainbenis: What are you doing before and after you find this condition? Do you have a work-around like clicking on the game screen to bring it back into focus?
Hburger: Chrome in particular has a lot of issues with keeping proper keyboard focus. We've got a few open bugs related to the issue, but we haven't been able to put the time into fixing them yet.
